If you bump in to the Periodic Table of Elements today, be sure to give it a hearty Mazel Tov, because it's just welcomed two new members to the family. Yesterday, the International Union of Pure and Applied Chemistry (IUPAC) officially recognized elements 114 and 116, crediting the discovery to scientists from Russia's Joint Institute for Nuclear Research and the Lawrence Livermore National Laboratory, in California. Boasting atomic masses of 289 and 292, respectively, the new man-made additions are now the heaviest elements on record, seizing the belt from copernicium (285) and roentgenium (272). As with most heavyweights, however, both decay within less than a second, making it difficult for researchers to get a grasp of their chemical properties. Nevertheless, both apparently had enough credibility to survive IUPAC's three-year review process, paving the way for the real fun to begin. At the moment, 114 and 116 are known, rather coldly, as ununquadium and ununhexium, respectively, though their names will eventually be jazzed up -- sort of. The Russian team has already proposed flerovium for 114 (after Soviet nuclear physicist Georgy Flyorov), and, for 116, the Moscow-inspired moscovium, which sounds more like an after shave for particularly macho chemists. IUPAC will have the final say on the matter, though one committee member said any proposed names are likely to be approved, as long as "it's not something too weird." Head past the break for a full, and somewhat obtuse PR.
